Thai Prime Minister Prayuth Chan-ocha has ordered to tighten security in Bangkok after two homemade pipe bombs exploded in the Siam Paragon shopping centre on February 2, slightly injuring two people.

The PM stressed the need to tighten security because this case involves the well-being of the people. He affirmed reporters that Thailand still needs martial law.

There was no claim of responsibility for the blasts.

Thailand has been under martial law since the coup toppled the government last May.-VNA
